I have Solomons Organic Chemistry 9th edition International edition because it was 150$ cheaper than US edition and its from what I hear the same book. If I buy the solutions manual will the questions match the answers? I appreciate your help, and would be thankful if anyone had any experience with this, or the US edition so that we could check problems/questions.(The book has lots of problems, very little solution/answers in the back...) Thanks again!
